If reports indicate the runway will be wet at ETA, what factor must be used in planning?

Explanation:
Wet conditions reduce braking effectiveness, so you must adjust the published dry landing distance to account for that extra stopping distance. The standard planning practice is to multiply the AFM’s Dry Landing Distance by 1.15 when the runway is reported wet. That 15% increase gives a conservative estimate to ensure you have enough distance to land and stop safely on a wet surface. The other options would either understate or overstate the required distance for typical wet conditions, so they aren’t used in this planning scenario.
